Avoid Save Conflicts Over the Web

Here is a cool method of avoiding the save conflicts over the Web. It is basically comparing the time the document was brought on to the Web and the time the document was saved last; if both are same then no conflicts else there is a conflict and make the save options field to "0" so the document is not saved.

Concept :- create a computed for display field named "Web_Modified" on the form with the default value as
"@If(@IsDocBeingSaved;Web_Modified;@ReplaceSubstring( @Text(@Modified) ; " " ; "_" ))

Add SaveOptions[Computed for display] field with default value as "1"

In the webquerysave run an agent which as the following.

set session = new NotesSession
Set db = session.currentdatabase
set thisdoc = session.documentcontext

If thisdoc.HasItem("Web_Modified") Then
If thisdoc.Web_Modified(0) <> "" Then
om = thisdoc.Web_Modified(0)
End If
End If

tmp = Evaluate( {@ReplaceSubString( @Text(@Modified) ; " " ; "_" )} , thisdoc )
nm = tmp(0)

If om = nm Then
" Continue , there is no save conflict ,
Else
"make saveOptions field to "0"
" give a alert box asking the user to resubmit the document

End If
